No matter whos fault it was bus/truck there have been a number of accidents at that location including at least one fatality - the hwy dips at that point and when you exit the car yard you are entering the hwy with traffic that is travelling at 80km/hr and they have just come over a hill. The sooner they put a service road to enter and exit those car yards like they have done to the car yard further back along the hwy the better.
